The process of files getting damaged as a consequence of some hardware or software failure is known as data corruption and this is among the main problems which web hosting companies face since the larger a hard disk is and the more data is filed on it, the much more likely it is for data to become corrupted. You can find a couple of fail-safes, yet often the data gets corrupted silently, so neither the file system, nor the administrators see anything. As a result, a corrupted file will be treated as a standard one and if the hard disk drive is a part of a RAID, that particular file will be copied on all other drives. In principle, this is for redundancy, but in practice the damage will get even worse. When a file gets damaged, it will be partly or fully unreadable, which means that a text file will not be readable, an image file will display a random blend of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your site content. Although the most widespread server file systems have various checks, they frequently fail to detect a problem early enough or require a vast time period in order to check all of the files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Website Hosting

The integrity of the data which you upload to your new cloud website hosting account will be ensured by the ZFS file system that we take advantage of on our cloud platform. Most of the internet hosting providers, like our firm, use multiple hard disks to store content and considering that the drives work in a RAID, identical info is synchronized between the drives all of the time. In case a file on a drive is damaged for whatever reason, however, it's likely that it will be reproduced on the other drives since other file systems don't feature special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy will be swapped with a good one from another hard drive. Due to the fact that this happens instantly, there's no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption as all our storage servers use the advanced ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, in order to verify the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives in a RAID i.e. the files will be the same across all disks. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it identifies a mismatch, which would indicate that one of the copies is corrupted, it will substitute that file with a healthy copy from one of the other drives. Even if there's a sudden power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, extending the time needed for the server to go back online. ZFS is the only file system that can really protect your content from silent data corruption.
